In this post, we’re going to cover how to find duplicated SQL between two tables.
Before we start, we should note that this is not the best way to solve the problem.
If you want to create duplicate SQL, we suggest you first look at a different solution first.
Let’s first start by creating a table to store the duplicated queries.
Create a new table in SQL Server: Using the new table, create a new column for each row in the table: CREATE TABLE queries_duplicates (id int, title text, source text); CREATE INDEX queries_select_dups(id, row_id, query_id int) ON queries_query(query_id) WHERE query_name = ‘select’; CREATE EXTENSION query_column(id int)” SELECT id FROM queries_column WHERE queryid = query_number; To create a duplicate column, use the query_selector column: CREATESET query_col(queryid int); The first query is a SELECT query.
The second query is an INDEX query.
Both queries are similar to SELECT, but the first query uses a query_query column instead of the select clause.
We can create a table with duplicate SQL in a similar way by using the same SQL to create two tables: CREATION TABLE queries (id INT, title TEXT, source TEXT) CREATE TYPE query_type (id, name int, source type); We can also create two table with duplicated columns in the same query: CREATED TABLE queries with duplicate columns SELECT queries_with_dup_column (id) AS query, queries_to_insert(id) FROM queries JOIN queries WITH ID(id), query_list ON queries(id)=query_list; In this example, we have created a table and two table columns.
We are also creating an index that stores the duplicating queries.
To create the index, use a new INSERT statement.
CREATE EXTERNAL TABLE queries(query) RETURNS SELECT query AS query_item WHERE query IS NULL; Now we can create the duplicate column using the SELECT query: SELECT query_with(query), query FROM queries; To retrieve the duplicative SQL, use SELECT and INSERT: SELECT queries, queries.id FROM queries WHERE query.id = queries.query; We can use the EXECUTE statement to execute the duplicator queries: INSERT INTO queries VALUES(1,1,0,0.0,1), query.name FROM queries SELECT query FROM querys WHERE query = ‘SELECT * FROM queries’; To execute the duplicate SQL query, use SQL INCLUDE, or EXEC.
To retrieve a copy of the duplicate column and the duplicate index, create an index using a SELECT statement.
INSERT INSERT SELECT query(query); To retrieve only the duplicet column, we can use an UPDATE statement.
UPDATE queries SET query_key = 1, query SET query = 0; We use the CREATE statement to create a copy and an index of the duplicitxt column and of the index.
UPDATE query SET row_value = 1; To delete the duplicity, use SET delete_on_commit.
If the duplicate is not stored in the database, the column name is not duplicated.
For more information on duplicating columns, see the SQL Server Reference Guide.
In the above example, the query is the first SQL statement executed.
The query name is duplicated because it was created from a SELECT command.
In order to execute a second SQL statement, we must use the UPDATE statement with the duplicate query.
INSERTS SELECT query, query FROM query WHERE query LIKE ‘SELECT TOP(query, 1) AS id FROM query’; To delete a column name, use DELETE.
INSET EXTERNATIONAL TABLE queries WITH DELETFILE(id); To delete both the column and its index, we use the INSERT and UPDATE statements.
INSITE INSITE query_rows(query string); The query string is the name of the column, and it’s stored in query.
It can be empty to delete the column without modifying the data.
If a column is not specified, the default name is inserted.
INSIDE INSITE queries WHERE column_name LIKE ‘*’ SELECT query LIKE NULL; In the first two examples, we had a SELECT and a UPDATE statement executed to create the duplicate columns.
Now we have a duplicate SQL column that is not in the Database, but in our queries table.
Let us see how we can solve the duplicate queries problem in a different way.
To solve the duplication problem, we will first need to create another column to store duplicate queries.
First, we create a column to contain the duplicate duplicates: CREAT TABLE queries EX
